UNTTED STATES JERRY JOHN SMITH, OF NORTH ADAMS, MASSACHUSETTS.

OIL BURNER.

Application filed November To all whom it may concern:

Be it known that T, JERRY 5. SMITH, a citizen of the United States of America. and a resident of North Adams in the county of Berkshire and State of lvlassachusetts, have invented a new and Improved Oil Burner, of which the following is a description.

My invention relates to a burner adapted to be employed in a stove or in a furnace.

The general object of the invention is to provide an oil burner eificient for the vaporizing of the oil and in. the production of a combustible mixture of air and oil vapor.

A more specific object of the invention is to provide a burner formed of parts, few in number and strong and durable and so constructed and arranged that the burner may be readily assembled or disassembled.

The nature of the invention and its distinguishing features and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a vertical section showing a burner embodying my invention and illustrating the same emplaced in a stove on the grate thereof;

Figure 2 is a plan view or the burner;

Figure 3 is a cross section through the burner as indicated by the line 33 of Figure 1.

In carrying out my invention in accordance with the illustrated example a hollow base 10 is provided having end openings 11 for the entrance at air and having longitudinal air outlet slots 12 at the sides. A central opening in the top of the base 10 is de lined by a collar 13. Said base in practice is made of a size to approximately cover the grate B of a stove A or a furnace. Cement or other packing material indicated at a may be disposed about the base 10 between the same and the walls of the lire box.

A ring 1% surrounds the collar 13 and forms a combustion chamber, said ring having annular series of air inlet orifices indicated at 15. On top of the combustion ring 14 rests a spider designated by the numeral 16 which is generally in the form of a ring having lateral arms 1'7 directed outwardly 2'7, 1923. Serial No. 677,284.

and resting on the top of ring 1 L. At the interior or the ring of the spider 16 lugs 18 are directed laterally inward.

Resting on the spider 16 is the burner head or nozzle having a bottom section 19 formed with arms 20 directed laterally outward to rest on the spider 16, said lugs being disposed slightly above the end surface of the bottom section 10 so that the latter enters between and is centered by the lugs 18. The top or upper section 21 of the burner head is in the form of a disk which in practice has a rib 22 thereon through which a transverse hole 23 extends to receive a sharp tool or device for lifting the disk. On the bottom section 19 of the burner head upstanding pins 242 project at diametrically opposite points said pins being receivable in grooves 25 formed diametrically opposite in the exterior of the disk 21. The pins serve to space the disk 21 from the bottom section 19 to leave open sides for the outlet oi? the burning products.

Oil is supplied from a tank or other convenient source to an oil pipe 26 having avalve 27. The pipe 26 connects as at 28 with a vaporizer pipe 29 extending upwardly and across the burner the terminal of the vaporizer pipe being returned and extending through the ring 2% at a side of the burner to the interior of said ring. The vaporizer pipe 29 adjacent to the connection 28 is supported in an upstanding lug 30 on the base 10 and said vaporizer pipe adjacent to its terminal tip 81 is supported 011 the top of said base 10.

The numeral C indicates asbestos wicking placed within the hollow base 10 on the bottom thereof directly below the central opening and therefore below the tip 31. In. practice oil is allowed to flow through the vaporizer pipe 29 and drip to the asbestos C or its equivalent. The oil is then lighted and the valve 27 closed. The result is that the vaporizer pipe 29 is heated to a high heat whereupon the valve 27 is opened to permit oil to flow in predetermined quantities to the pipe 29 where it becomes vaporized and issues in vapor form from the tip 31.

In the operation of the burner the ring 14L forms a mixing chamber for the air and vaporized oil while the hollow lower section 19 or" the burner A forms a combustion chamber below the disk 21 from which combustion chamber a duplex flame issues and rises at the sides of the vaporizer pipe 29 cffectively heating the latter.

The described construction permits of the burner being rapidly assembled and disassembled, the construction permitting the burner to be completely taken apart.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim:

1. In a, burner, a hollow base having an inlet for air and having at the top thereof an approximately central opening as well as longitudinal outlet slots at the sides of the base, a ring seating on said base at said central opening and having openings for the inlet of air, 'a'supporthaving lateral arms resting on said ring, said support being opened for the outflow of air and oil vapor, and a burner head formed of separable upper and lower sections, the upper section being in the form of a disk, upstanding pins on the lower section engaging the said disk and supporting the latter elevated to provide outlet passages for the combustible mixture at opposite sides of the head, said lower section having lateral members resting on said support and the support having centering lugs within which said lower section is received; together with a vaporlzing pipe extending above the burner across the burner he'ad thereof, said vaporizing pipe being return bent and extending through said ring at a side thereof to the mixing chamber within, and a tip on the terminal of said vaporizer pipe.

2. In a burner, a base having an air inlet and an outlet at the top, a ring removably seated on said base about said opening, supporting means detachably resting on said ring, a burner head removably seated on said supporting means, said supporting me'ans having centering means within which the lower portion of said burner head is received, said burner head forming a combustion chamber having an outlet for the burning mixture, and a vaporizing pipe extending across the burner above said head and discharging within said ring.

JERRY JOHN SMITH.
